Due to the Twin-piston system the force developed by the counter-running pistons is transmitted to one common pinion via too tooth rack solidly connect with the pistons. This principle ensures a linear torque transmission a long the entire stroke.

ZK series ball valve is 1-piece designed wafer-type ball valve, full bore, mounting pad for actuator according to ISO 5211, Anti Static Device. TA Luft approval up to DN100.

CHARACTERISTICS

• extra small dimensions.
• low weight
• direct actuator mounting possible.
• low dead spot at container mounting.
• blow-out proofed stem.

OPERATION

Flange DN15…DN200.

DN15…DN50: measured to PN40.

DN65…DN200: measured to PN16.

Flange produced with threaded holes,

Ball valve DN65 will be delivered in 4-hole execution!

PRESSURE RANGE

Almost vacuum up to nominal pressure(max. +80°C).

For higher temperatures please refer to the Pressure -Temperature-Diagram.

TEMPERATURE RANGE

-30°C…+180°C.

At media temperature above 80°C or large oscillating media temperatures we recommend a pressure compensation bore in the ball. At media which tend to steam-building the pressure compensation bore is compellingly required. Please mention in your order.
